We're in the middle of a pandemic. You're not working from home; you're at home during a crisis, trying to work, and homeschool, and not lose your sh*t. You don't necessarily have all this "extra time," you have time that is difficult to cope with at the moment for various reasons and we're all being impacted differently.
You will have bad times and you will have better times throughout this pandemic. Take advantage of the better times. It's okay to go easy on yourself during the bad times. Remember: This is temporary.
Do your best to still take care of your wellness while not pushing yourself too hard.
